5.5. Graphical time/allocation profile

You can view the time and allocation profiling graph of your
program graphically, using ghcprof. This is a

To run ghcprof, you need
uDraw(Graph)™ installed, which can be
obtained from uDraw(Graph). Install one of
the binary
distributions, and set your
UDG_HOME environment variable to point to the
